Introduction Electron spin resonance (ESR)1 has developed over the past several decades as a technique to provide information on the electronic structure of organic, inorganic, biological, solid state, and surface molecular species. The article concludes with an introduction to stochastic EPR which makes use of another concept for investigating resonance systems in order to increase the excitation bandwidth of pulsed EPR. • Chemists are mostly interested in two main pieces of information: g-values and hyperfine couplings, though spin-relaxation information can also be important to more advanced practitioners. EPR has many important applications in the study of organic radicals, paramagnetic inorganic complexes, and bioinorganic chemistry. Electron spin resonance spectroscopy (ESR) or electron paramagnetic resonance (EPR) is a technique for studying chemical species that have one or more unpaired electrons, such as organic and inorganic free radicals or inorganic complexes possessing a transition metal ion. 2, Chapter 1 by Solomon and Hanson. These include organic free radicals,2 biradicals, Experiment #2B: Electron Spin Resonance Spectroscopy I. EPR: Chapters 9 and 13. ELECTRON PARAMAGNETIC RESONANCE SPECTROSCOPY (EPR) LECTURE NOTES: DR. CYRIAC MATHEW Lecture notes: Dr. Cyriac Mathew EPR spectroscopy is applicable to species (atoms, molecules or ions) containing one or more electrons with unpaired spins, and is observed in the microwave region of electromagnetic radiation. The limited excitation bandwidth of pulses at high frequency is one of the main limitations which, so far, made Fourier transform methods hardly feasible. Majority of stable molecules are held together by … NMR and ESR Spectroscopy K. R. Shamasundar and M. Nooijen University of Waterloo Introduction Nuclear Magnetic Resonance (NMR) spectroscopy and Electron Spin Resonance (ESR) spectroscopy are two widely used spectroscopic techniques to infer structure and properties of complex molecules (even bio-molecules such as proteins). Background references: § Orton, Electron Paramagnetic Resonance; § Abragam & Bleaney … Hence, the lectures on EPR spectroscopy build on material that has been introduced before Lecture 37: Quantum mechanical description of beam splitters Lecture 38: Single photon interferometry Lecture 39: More on single photon interferometry Lecture 40: Entanglement Lecture 41: Bell’s inequality and the EPR argument Lecture 42: Optical tests of the EPR experiment: violations of the Bell’s inequality MiniProjects 1,2,3,4, and 5 Also good: Inorganic Electronic Structure and Spectroscopy, Vol. This lecture course introduces the basics for applying EPR spectroscopy on reactive or catalytically active species as well as on spin probes. Electron paramagnetic resonance, or EPR, spectroscopy is an important technique for the characterization of paramagnetic compounds, such as compounds with unpaired electrons.
